3.3 Audio continuity test (
1. Connect the measurement cables to the unit terminals.
2. Set the rotary switch to position "
3. Connect the unit to the circuit to be tested. The buzzer is
continuously active as soon as contact is established (circuit
closed) and if the resistance value measured is lower than
the threshold value chosen by the programming (adjustable
from 1 to 40 Ω, see § 03.12.10).
Above 400 Ω, the display indicates OL .
Cable resistance compensation (Ω Ω Ω Ω Ω zero)
To measure low resistance values, measure the cable
resistance first.
- Short-circuit the cables.
- Press and hold the HOLD key until zero appears on the
display. The cable resistance value will then be memorised
and subtracted from the value of the resistance measured
later.
Note: If the value measured is higher than 2 Ω , this
correction is stopped and the memorised correction
value is reset to zero.
